You can bring some goods from abroad without having to pay UK tax or ‘duty’ (customs charges), as long as they are for your own use.
If you are coming:
from a European Union (EU) country you can bring in an unlimited amount of most goods
from outside the EU you can only bring in a certain amount without paying duty or tax - up to your duty-free allowance
There will be no change to the rights and status of EU citizens currently living in the UK until 30 June 2021. You and your family can apply to the EU Settlement Scheme to continue living in the UK.
You must tell customs about (‘declare’) any other goods when you arrive at the UK border, as well as anything that is banned or restricted in the UK. If you owe any duty or tax, you will usually have to pay it immediately.
Your goods and any vehicle you use to transport them may be seized if you break the rules. You may also be fined or prosecuted.
You can report someone for breaking the rules to HM Revenue and Customs (HMRC).
